请帮我把这句中文翻译成英文我需要翻译结果学术一些符合论文投稿风格我想翻译的句子是：小白菊内酯parthenolidePTL一种从中药小白菊的叶子中提取得到的倍半萜烯内酯类天然产物表现出良好的抗肿瘤活性然而PTL对宫颈癌的作用及分子机制尚不清楚。我们的研究结果显示PTL能明显抑制宫颈癌细胞HeLa和SiHa的增殖且呈浓度和时间依赖性。此外PTL通过抑制VEGF、MTA1、TGF-β1的表达显著抑制宫

Parthenolide (PTL), a sesquiterpene lactone natural product extracted from the leaves of the traditional Chinese medicine feverfew, exhibits excellent anti-tumor activity. However, the effect and molecular mechanism of PTL on cervical cancer is still unclear. Our research results show that PTL can significantly inhibit the proliferation of cervical cancer cells HeLa and SiHa, and exhibits concentration and time dependence. In addition, PTL can significantly inhibit the migration of cervical cancer cells by suppressing the expression of VEGF, MTA1, and TGF-β1.
